To all whom it may-concern:

Be it known that 1, JOHN Hroxs, 'a subject of the King of Great Britain, residing at Calgary, in the Province of Alberta, and Dominion of Canada, have invented new useful Improvements in GasBurners for Furnaces, of which thefollowing is a specification. v

This invention relates to heating devices and particularly to mixing and combustion chambers for use in connection with hot air furnaces, vertical boilers, hot water heating and the like.

The primary object of the invention is to.

provide an auxiliary combustion and mixing chamber which may be placed upon a stove or furnacefland supported upon the grate bars in a manner to permit gas orother fuel being supplied thereto, said chamber embodying a base, skeleton ribs, a mantle preferably formed of thorium supported upon said rlbs, .the ribs having pro ections for engagement of the mantle the whole mixture and combustion, for the purpose of forming a dome shaped mixing chamber in which the-gas and air are held for'proper heat generation? Other objects and advantages of the invention will appear from the followingidescription, when read in connection with the accompanying drawings, in which- Figure 1 is a vertical sectional view through a furnace having the invention applied thereto;

Fig. 2 is an enlarged central vertical sectional view of the combined combustion and mixing chamber; and

Fi 3 is a top plan view with part of the mant e broken away;

In the drawings, there is illustrated a hot air furnace of any approved type, which 1s provided with the usual firebox or combuschamber 12-.

I Specification of Letters Patent.

Applioationflled April 27, 1917. Serial No. 165,005.

of the ribs 11 are other ribs or flanges 11', which extend from a point approximately centrally of the length of. the dome. In practice when the burners are lighted, the flame strikes the inside ribs 11 and is remixed and diffused. equally all over the inside of the combustion chamber, otherwise, with the use of the natural gas, the top of the mantle would be blown off.

The ribs 11 have formed upon their outer edges a series of projections 14: for the'purpose of aiding in holding and supporting the gas mantle 15, which is adapted to be positioned over the ribs to complete the mixing chamber, the said gas mantle being pref erably formed of metallic thorium.

Suitable burners 16 are adapted to supply gas or other fuel within the mixing cham- "ber, valves 17 being provided for the purpose of' controlling these burners.

The right is reserved to make such changes in the form and proportion of the invention as will fall within the scope of the claims hereto appended.

Having described the invention, what is claimed is:

1. A combustion chamber embodying a dome shaped skeleton frame composed of diametrically disposed archshaped ribs, a

gas mantle adapted to cover said ribs and projections carried by said ribs for engagement with the gas mantle.

- 2. A combustion chamber embodying a dome shaped skeleton frame composed of diametrically disposed ribs, a gas mantle adapted to cover said ribs and projections carried by the said ribs for engagement with the gas mantle.

3. The combination with a furnace, of an auxiliary combustion chamber adapted 'to be supported upon the grate thereof, said chamber embodying a dome shaped skeleton frame composed of diametrically disposed arch shaped ribs, a gas mantle adapted to cover said ribs and means carried.by\said ribs for engagement with the mantle.

4:. A combustion-chamber embodying a skeleton frame, a gas mantle positioned. over saidf'rame and meanslocated within said 1 chamber for remixing and, didusing the gases.

5. A combustion chamber embodying a skeleton'frame, a gas mantle positioned over said frame and means includin diametrically arranged ribs located within the comltd Milt

the gases.

remixing and diflusing 6. A combustion chamber embodying a 1 skeleton frame,

5 said frame and a gas mantle positioned over a removable base supportmg said frame to permit of the independent expansion and c0 ntraetion of the frame.

' 7. A combustion chamber embodying a skeleton frame, a gas mantle positioned over said frame and means located Within the gas 10 mantle for renfixingggand diifusing the gases.

In testimony whereof I aflix my signature.

JOHN HICKS.
